Resumen de Parametric and Semiparametric approaches in the estimation of a job-search model.

A. Fernández, Juan M. Rodríguez-Poo

• This paper analyzes empirically the labor supply in the spanish labor market using different econometric techniques to estimate the reduced form models. Mainly we use maximum likelihood and two step estimation methods under different assumptions as heteroskedasticity and non-normality. Among two step methods we consider the approach developed by Heckman and other two step estimation procedures based on semiparametric methods. We also perform several specification tests and we compare the results obtained under different specifications.
